You first select "What's this?" if it's available (not always provided
and sometimes it's a simple "?" next to the window's minimize button).
Then you select the "leaf" menu item of interest (ie. menus with
submenus don't trigger the "What's this?").  The menu remains open
during and after the tooltip is shown.

I'm not sure that C-h k should be bent to showing tooltips as C-h k on
a menu item already invokes describe-key and having two different
styles of output for it might be confusing.  In general, you want to
make the tooltip simple to get to, but not constantly popping up in
your way.  My suggestion would be to make the first character of the
menubar (or modeline?) a "?" which would serve as this "What's this?"
button (the equivalent Emacs command can be pretty obscure).  Menus
generally aren't available in non-windows mode (correct?) and you
don't need tooltips in non-windows mode (correct?), so, when the menu
goes away, easy access to tooltips would also go away and this would
be reasonable.

Are tooltips reasonably applied to anything other than (the equivalent
of) an XWindow widget (menu item, button, frame, etc.)?
